I didn't see any recipes for puddings on the list of trail foods nor any recipes that required pudding bags. In the 18th century puddings were quite common and so was the use of pudding bags. Men in military service were issued cloth for pudding bags and they were used at home. Suet Puddings, Bread puddings, and peas puddings are all great sources of calories, which of course is great fuel for us while on winter scouts or on long stints at rowing or whatever. To make pudding bags, needed: a quantity of hemp, linen or cotton thread, a quantity of hemp or linen cloth. Objective: to make bags with different volumes. Ok, so lets plan to make Dogs body so you will need a bag that will hold 1lb of pease very loosely. So fill a paper or plastic bag with 2lbs of pease and that will give you an idea of what size bag you will need. Get your linen or hemp cloth and make a pattern for your bag, this is not rocket science, the bag could be made by cutting a rectagular piece of cloth, which could then be folded so that the fold becomes the bottom, then the sides could be sewn up with your linen thread and the opening is then hemmed. The bag is made out-side in and has to be turn inside out when you've finished your bag. Use some linen string to tie the opening of the bag shut. I'll give you the recipe and methord of cooking a pease porridge next time. I'm sure many of you use similar bags for food containment. Paul
